Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This proposal relates to a lid attachment / detachment detection device in a lid removal device for a coal charging vehicle installed at the top of a coke oven.

[0002]

[Prior art]

 Conventionally, as shown in Japanese Utility Model Laid-Open No. 58-22948 and Japanese Utility Model Laid-Open No. 1-119031, the coke oven lid removal confirmation device for a coke oven detects a lid attached to a lifting magnet with a touch sensor.

However, the lifting magnet and the lid attracted thereto are not always aligned with each other in core, but are usually attracted in a state where the core is considerably displaced.

At the position where the core is displaced, either the position of the attracted lid and the touch sensor are not in contact with each other or the touch sensor is damaged even if the contact is made, and the lid is attracted to the lifting magnet. There was a problem that it was virtually impossible to confirm whether or not it was.

[0005]

[Problems to be solved by the device]

 The idea is to confirm the attachment / detachment of the lifting magnet and the lifting magnet even if the cores of the lifting magnet and the lid attracted to it are completely deviated, and obtain a device that can automatically move to the next process by the confirmation signal. That is the purpose.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, this proposal provides a support frame with a vertical guide guide on the furnace top traveling machine frame, and a forward / backward traveling main body supporting the rear wheel on the upper guide guide and the front wheel on the lower guide guide on the support frame. In the lid removing device of a coal-charging vehicle, which is provided with a lifting magnet that can be raised and lowered freely in front of the main body, and the lifting magnet is moved up and down and the forward and backward movement operation device of the main body is provided, a wheel pressure fitting is provided on the guide guide. , A lid removal / detection device in a lid removing device of a coal-charging vehicle provided with an electronic weighing device for a wheel load applied to the pressure-receiving metal fitting. Detecting device The wheel pressure fitting is constituted by the lid attachment / detachment detecting device in the lid removing device of the coal charging vehicle according to the first aspect of the invention, in which the front wheel pressure fitting is the front wheel pressure fitting.

[0007]

[Action]

 In this plan, the coal car is stopped at the top of the coke oven, and in this state, the forward / backward moving body moves forward from the rear end position to the front end position along the vertical guide of the support frame. At the rear end position of the main body, the lid is not attracted to the front lifting magnet (hereinafter referred to as the "lift magnet"), so that the pushing-up pressure of the rear wheel applied to the pressure receiving fitting is lowered.

[0008] After or after the advance, the riff mag descends onto the lid, and the lid can be attracted by magnetic force. With this adsorption, it does not matter if the riff mag and the lid are misaligned.

After that, after raising the riff-mag above the loading port by the lifting device, the front wheel of the main body is supported by the lower guide guide and the rear wheel is supported by the upper guide guide to move backward to the rear end of the support frame. The front and rear wheels are stopped at positions where the wheel pressure fittings are pressed downward or upward (the state where the rear wheels are pressed upward is shown in FIG. 2).

In this state, the load by which the front and rear wheels push the wheel pressure fitting downward or upward includes the weight of the lid adsorbed on the front riffmag, and the electronic weighing device measures the weight increase of the lid and issues a weighing signal. It is possible to issue a command signal for operating the program control device by the signal, lowering the smoke hood in the next step, and lowering the charging sleeve toward the charging port.

【Example】

 A machine frame 9 of a coal car 4 running and stopping on a rail laid on the top 8'of the coke oven 8 is provided with a chain 11, 11 for suspending and supporting a front-rear direction support frame 10 having vertical guides 1, 1 '. The front-rear traveling body 12 is supported on the support frame 10 by the front-rear wheels 13 and 14 so as to be able to reciprocate.

A support ring 16 is provided in the front of the main body 12 so as to be able to move up and down via parallel elevator links 15, 15, and the riff mag 6 is rotatably supported in the support ring 16. The front wheel 13 of the main body 12 is supported downward on the upper surface of the lower guide guide 1'by the weight of the parallel links 15, 15, the support ring 16, the riff mag 6, and the like, and the rear wheel 14 of the upper guide guide 1 '. It is supported upward on the lower surface.

[Effect of device]

 Since the present invention is configured as described above, in the lid removing device for the coal car of the coke oven, the lid of the inlet is adsorbed by the front riff mug and rises, and in that state, immediately or when the lid removing device moves backward or to the predetermined position. In the retracted state, the weight of the lid is measured or sensed by the electronic weighing device via the wheel pressure fitting regardless of the misalignment between the riff mug and the lid, so it was confirmed that the charging port was opened securely. Moreover, there is an effect that an electric signal can be emitted to safely move to the next lowering of the hood or the loading sleeve.
